ATI Exit Exam 2023 Quizlet

Correct Answer: C

Rationale: The correct answer is C: Decreased serum ammonia. Lactulose is prescribed to decrease serum ammonia levels in clients with cirrhosis and hepatic encephalopathy. By reducing serum ammonia, lactulose helps improve the mental status of these clients. Therefore, monitoring for decreased serum ammonia is crucial to assess the effectiveness of lactulose therapy. Choice A (Improved mental status) is indirectly related as it is the desired outcome of decreasing ammonia levels. Choices B (Increased urine output) and D (Decreased bilirubin levels) are not directly associated with the therapeutic effects of lactulose in cirrhosis and hepatic encephalopathy.

Correct Answer: B

Rationale: Polyuria is the correct answer. Diabetes insipidus is characterized by the inability to concentrate urine, leading to excessive urination (polyuria) and thirst. Bradycardia (slow heart rate) is not typically associated with diabetes insipidus. While dehydration from the excessive urination can lead to hypotension rather than hypertension, and weight loss can occur due to fluid loss, the most specific and significant finding expected in diabetes insipidus is polyuria.

Correct Answer: A

Rationale: The correct answer is A: 'Wear low-heeled shoes.' Wearing low-heeled shoes helps prevent back strain by promoting proper posture. High heels can cause an imbalance in the body's alignment, leading to increased stress on the lower back. Choices B, C, and D are incorrect. Elevating the legs while sitting can help with circulation but does not directly prevent low back pain. Engaging in prolonged sitting can actually contribute to low back pain due to decreased muscle activity and increased pressure on the spine. Sleeping on a soft mattress may not provide adequate support for the back, potentially worsening back pain instead of preventing it.

Correct Answer: B

Rationale: Swelling of the arm above the insertion site is concerning as it can indicate complications like thrombosis, which require immediate attention. Redness at the insertion site is common and expected in the initial stages. A bruised area around the insertion site may result from the insertion procedure and is usually not alarming unless it worsens or becomes larger. A temperature of 37.2�C (99�F) is within the normal range and is not directly related to PICC complications.

Correct Answer: B

Rationale: The correct answer is to change the TPN tubing every 24 hours. This action helps reduce the risk of infection because the high glucose content of TPN promotes bacterial growth. Choice A is incorrect as changing the tubing every 48 hours would not provide adequate infection prevention. Option C, monitoring urine output, is important for assessing renal function but is not directly related to preventing TPN-related infections. Option D, monitoring weight, is essential for assessing nutritional status but does not directly address infection prevention in TPN administration.
